A multipath routing survey for mobile ad-hoc networks

Mobile ad hoc networks (MANETs) pose particular challenges in terms of Quality of Service (QoS) and performance. This is due to the effect of numerous parameters such as; bandwidth and power constrains, delays, security issues, etc. On the there hand, the degree of freedom enables the wireless mobile nodes to enter and leave the network dynamically. The latter offers redundant paths and dynamic coverage. Particular attention is given to the multipath transmission capability as well as load balancing to have efficient routing possible for heavy multimedia traffics. In this paper, the issues of multipath routing in MANETs are surveyed and performances of such MANETs are compared to discuss the application of multipath routing and its effects on different layers to support QoS. © 2005 IEEE.
